Quote:I would say mine middle of the road slew wise - pretty quiet while tracking, but my mach1 isn't exactly quiet either when I slew (cant hear it tracking by comparison). Are loaded up with the gear in your sigline?
Quote:512x is pretty good. the atlas slews at a maximum of 800x.and the luckless folks with Takahashi Temma2 Jr. slew at... 120x.

Quote: Servo motors if they are stalled / jammed and the motor control circuit is not properly done, you can burn out either the motor or the circuit (a known problem on CGEM's).

Quote:Ed, the CGEM I currently have had went back for warranty repair for a busted motor board (according to the previous owner).I have also "heard" of others with the same issue. In fact isn't that the whole point of the uprated H-bridge in the CGEM DX? the DX has the same motors (according to Derick over on TeamCelestron) so certainly looks like a "known problem" to me.I've heard of similar issues with Gemini 1 servos.Funny one never hears about burned out Mach1 motor boards or motors though. Seems that a properly designed servo controller shouldn't blindly up the current when it detects a stall or slowdown.
Quote:I was fortunate to have some nice skies last night so when I was out observing I listened closely again to my iEQ45. It's nearly silent while tracking and slewing is not anything that I would describe as loud.

". . . looks like its time to dissassemble and see if something is wrong."
Is it time to dismantle and see if something it wrong?
And probably void the warranty in the process?
Or is it time to take advantage of the iOptron return policy and send it back for a refund?
Sounds like you are not getting the support from iOptron you should be getting. To be told "some are noisier" is a very poor comment on their Quality Control and on their customer support.
